This is a great idea and there's lots of info out there on it!

The average rider will produce between 125 and 200 watts using the Pedal-a-Watt. While this may not seem like much power, many pieces of equipment draw very little power and can be powered for long spans of time with small amounts of power.
Lights, laptops, and radios all draw small amounts of current at 12 volts DC. In addition, LED lighting and high efficiency fluorescent lighting now allow 200 watts to go a long way. A typical 25 watt fluorescent light bulb, which replaces a 100 watt incandescent bulb, will last 8 hours on 200 watts worth of power. LEDs (light emitting diodes) are even more efficient and will last days on 200 watts worth of power.
Want to know if you can power an appliance? Look at the label on the rear (usually by the power cord) and find out the "rating" which is in watts. For example, the label may read 30 W under electrical rating and this is 30 watts. If you are unsure, please email us with questions.
Power Consumption of Typical Appliances:

Small TV 100 watts
Large TV 200 watts
Laptop PC 10 watts
Desktop PC 75 watts
Stereo 20 watts
Charging a cellphone 5 watts
Hi Effic Desk lamp 15 watts

Any bicycle that is in good shape will suffice for mating to the Pedal-a-Watt platform. However, bicycles with wheels of larger diameters, such as 27 inches as opposed to 16 inches, create more mechanical advantage. Both street bikes, with very narrow, smooth tires, and mountain bikes, with wide, knobby tires, have been used with equal success.

Watts is an instantaneous measure of power at any moment in time. Watt-hours is a measure of power over time.

For example, the Pedal-A-Watt, creates 200 watts of power. If you pedal for 2 hours, then you have created 400 watt-hours ( 200 watts x 2 hours) of power.

This 400 watt-hours would power a 100 watt light bulb for 4 hours, a 200 watt large screen TV for 2 hours and so on.
This is just amazing.

2. Create a New Generation for Reversing Global Warming Club
3. Conduct study tours to share relevant experiences
4. Organize youth camps focusing on reduction of energy consumption
5. Establish a service center for bicycles
6. Hold mobile forums to teach peers in five villages about the benefits of bicycle use
7. Launch a radio campaign advocating bicycle use on National Mothers’ Day

Anticipated outputs:
1. Emergence of a youth group with an action plan to create value through bicycle use and energy efficiency
2. Adoption of bicycles for short-distance commuting in 30% of total population
3. Within two years of project start: (1) 30% reduction in use of motorbikes for commuting to school, and (2) avoided consumption of 18,072 litres of gasoline; this is equal to THB 433,728 and 39,758,000 grammes of CO2
4. Community-wide awareness of the environmental benefits of bicycle use

Project Results
I. First progress report (September 12, 2006):
Activities undertaken:
1. Training provided for 50 core youth leaders
2. New Generation for Reversing Global Warming Club created
3. ‘Bicycles to Reverse Global Warming Festival’ held
4. Community radio programme launched

Results of activities:
1. 30 project members planned the ‘Bicycles to reverse Global Warming Festival’; 189 people—on 150 bicycles—participated
2. 74 project members formulated an action plan and methodology for data collection
3. Increasing percentage of the population showed interest in project activities, and participating in the campaign

II. Mid-course evaluation workshop (February 20-22, 2007):
After a brief presentation by the National Coordinator (NC) reiterating the objectives of the GEF SGP, representatives from each project spent 30 minutes explaining project background, activities undertaken, immediate results and challenges. The National Coordinator encouraged candid discussion of problems and problem-solving strategies, and each presentation was followed by a question-and-answer session.

Project representatives also spent an afternoon interacting with community members from THA-05-14 (Local Scenes for Environment Protection). Workshop attendants learned about the old ways of life in the central area and how local ecologies had been altered. The final day was allotted to the two remaining project presentations, the National Steering Committee's observations and suggestions, and the National Coordinator's reminder of next steps.

Progress-related observations at Workshop:
--Of 14 projects, 12 were on time regarding activities and submission of reports. All were capable of articulating details of their activities and immediate results, which were deemed promising.
--Several projects secured financial support from other stakeholders.
--Leaders from at least four projects demonstrated increased capacity, both technically and institutionally. (National Steering Committee members expressed special satisfaction with this.)
--Eleven projects used Power Point and audio-visual equipment; the remaining three presented sets of photos.

III. Second progress report (March 7, 2007):
Activities undertaken:
1. Continued training for 50 core youth leaders
2. Training camp held for members of the New Generation Club to Reverse Global Warming
3. Centre for Bicycle Service Against Global Warming established

Results of activities:
1. 20 leaders show increased capacity as a result of role in planning activities of youth groups
2. 136 project members show increased capacity as a result of participation in organized events, and role in disseminating project information to communities outside target area
3. Centre served 20 bicycles, and had another 20 donated from the community

IV. Interim report (September 18, 2007):
The report highlighted two events:
(1) Cycling Against Global Warming Campaign
(2) Mobile Forums for Training Brothers and Sisters To Cycle

Cycling Against Global Warming Campaign: This secondary campaign encompassed 221 participants from the New Generation of Wang Noi (Tha Nang Naew School), the Phu Tham Phu Kratae Forest Conservation Group, and youths from Wang Noi District. These participants shared knowledge, built networks, performed bicycle repair services, and engaged in a rally for environment.

Mobile Forums for Training Brothers and Sisters To Cycle: The Mobile Forums took place in six villages, and reached 270 people, 60% of which were children. The four major activities were: reforestation of marginal area and temple grounds, environmental education, demonstration of bicycle maintenance, and bicycle service for those attending. As a result of these forums, friendships were forged, over 1,000 trees were planted on temple grounds, and old bicycles were made usable again.

V. Monitoring visit from NC and two NSC members (April 10, 2008):
On April 10th, the National Coordinator and two members of the National Steering Committee visited THA-05-21 to assess project results, and interact with the target population and other stakeholders to gauge their satisfaction. The two-year project is nearing completion in several months.

In discussions with project members, the assessment team discovered a number of issues that had reduced project effectiveness. These included:
• After initial campaigning and training, hundreds of students were using bicycles to commute to school. Soon afterwards, rumors about gangs using vans to kidnap children riding bikes prompted commuters to turn to car-pooling (subsidized by the local Tambol Administrative Organization, or TAO).
• A lack of bike lanes along roads connecting villages to schools made cycling dangerous for students.
• A number of parents encouraged their children to use motorbikes, as they are more comfortable and efficient.
Despite these issues, the project youth group and some community elders were using bikes to do errands within the village.

Project leaders were working towards project sustainability by convincing participating schools to establish bicycle service centers, and soliciting institutional and financial support from the TAO for promoting bicycle use.

After these discussions of project issues and action plans, the assessment team cycled 10 km with students and other villagers to plant trees in a local school. As the school is near a previous SGP grantee--THA-98-G20, ‘Rehabilitation & Conservation of Phu Tham & Phu Kratae Forest’--they were also able to verify that the forest has been well rehabilitated in the nine years since project end.

4. Training additional youth groups in five villages and one municipality
5. Disseminating project results through community radio, national mother’s day and printed matters on energy conservation

Results:
1. Emergence of a youth group called New Generation Club to reduce energy consumption to reverse global warming, with planned participatory system to include new junior groups and relevant local administrative organization to sustain project activities
2. Evinced increasing numbers of bicycle use, from average 7 persons/day to 13 in two target villages ( Baan Pa Peng and Baan Namsub)
3. 63 bicycles being donated by individuals with estimated value of Baht: 9,450 , increasing bicycle users to 100 persons
4. Estimated avoidance of gasoline use by 3,375 litres during the life of project. This could be translated to an equivalent amount of 7,425 kg. of CO2.

Impact: 1. Local government offices such as public health office, municipality and tambol administrative organization encourage, through
participatory process, community members to use bicycle for short-distance mobility.
2. The management of four primary schools established bicycle repairing centres with a goal to upscale throughout all primary schools in
Waeng Noi District.
3. Tha Nang Naew DJ Club was committed to continue with project dissemination.
4. Project activities were sustained through the support of the Health Promotion Fund of the government.

Experience and lessons learnt:

In campaigning on bicycle use, continuity was of utmost important. Target communities needed to be regularly instigated to ensure sustainability and successful transfer of practice from this generation to next. With able youth groups, the successful transfer was expected. Primary schools should be more targeted than secondary ones to ensure transfer of built capacity thus continuity. In this regard, the project, together with its network, had formulated a bicycle curriculum for primary schools with appreciated number of biking students.

This is it. this is another perfect example of something that is out there and ready to use. Their success is inspiring.

About Us

We are a non-governmental organization located in San Andrés Itzapa, Chimaltenango, Guatemala. We started in 1997, working with a group of Canadians from the organization PEDAL. Following a vision for sustainable development in Guatemala, we became constituted under local control as Asociación Maya Pedal in 2001. We recycle used bicycles to build pedal-powered machines, bicimáquinas, which support and help facilitate the work of small-scale, self-sustainable projects. Through this work we hope to contribute to the conservation of the environment, the health or the Guatemalan people, and the productivity of the local economy.

Mission and Vision

To support the basic family economy, through the design and distribution of bicycle machines, providing an efficient alternative for the rural development of Guatemala.

To be a non-governmental organization that promotes the use of bicycle machines through programs, projects, partnerships, activities, and actions, also promoting the use of alternative transportion using bicycles and tricycles

Objectives

  • To recycle and reuse bicycles.
  • To design and produce pedal-powered machines that meet the necessities of communities.
  • To raise consciousness, to educate, and to inform communities about the use of pedal-powered technology as an element of ecological sustainability.
  • To produce, promote, and commercialize bicycle machines and the products made with them, with the ultimate purpose of being a self-sustainable organization, and to help associated groups also achieve this goal.
  • To establish alliances with national and international groups that have similar goals and that have the capacity to transfer pedal-powered technology to other areas of the world.
  • To distribute pedal-powered machines for use in peasant agriculture, domestic work, and small business.
  • To contribute to the local economy, to improve productivity, health, and the surrounding environments of rural families.
  • To share the experiences of the organization through community-based environmental education, and print articles about the benefits of pedal-powered technology.
  • To develop technology that does not rely on energy sources such as electricity, fossil fuels, or on agro-industrial techniques.
  • And to conserve our environment.


Moving Windmills


Here is a video that my father sent me, it has changed the way I am looking at my thesis project. This is a windmill built with a great deal of bike parts. It was built by someone who had no other tools then what was around him, that is where innovation comes from.

http://movingwindmills.org/

Moving Windmills Project supports Malawian-run rural economic development and education projects in Malawi, with the goals of community economic independence and self-sustainability; food, water and health security; and educational success. Moving Windmills Project is inspired by the story of William Kamkwamba, a remarkable young man from a remote village north of Malawi’s capital city. Forced to drop out of school due to lack of funds, William turned to self-education and, after seeing a picture of a windmill in a textbook, decided to build one to power his family’s home.
